Do you have some news about the report project ?  I didn't obtain results
with reports, it generates empty. :(

And I need to analyse the alerts in detail. I need to identify if alerts are
scan ou what kind of attacks, or if they are false positives. Do you
understand me?

The logs are not enough to obtain these information.

The report generation component of Bro is very much still in the "pre-
alpha" stages, and the student
who was working on this is now working on another project.

I'll try to answer a couple of your questions:

1) scan reporting is off by default, the reports were too long with
all the scans included
      (Im not sure how to turn them on)
2) by default, the report scripts look for "yesterdays" data, so you
have to collect 1 days data,
then run the report
3) there should be nothing in the /usr/local/bro/archive directory
unless you are running
the cron script: bro_log_compress.sh

You'll likely need to modify the report generation scripts by hand to
get them to generate
exactly what you want.

Hope this helps.
